研究兴趣和材料体系:

低维轻元素量子材料的可控制备和性质研究

不同于其三维构型,二维材料“所有原子都暴露在表面”使得可以Atom-by-Atom精准解析结构,在二维空间中揭示原子尺度上的新型构效关系也成为可能。通过bottom-up的精准生长控制和top-down的人工堆叠制造,课题组的研究兴趣聚焦在轻元素量子材料及其异质结构,探索其本征的电、光、热、磁性质、调控手段和潜在应用。诚挚欢迎喜欢“Do Something New, Do Something Different”的博士后、研究生和本科生加入我们。

目前关注的体系包括(不限于):

1)二维体系中的同位素效应

2)新型二维轻元素量子材料

3)轻元素无序材料


研究成果:

获国家自然科学基金项目、国家重点研发计划、北京市自然科学基金项目等资助,发表科研论文超过50篇,其中包括Science、Nature子刊、PNAS、PRL、JACS、Adv. Mater.、ACS Nano、Nano Lett.等。多项工作被媒体报道和期刊高亮评论(Science、NPG Asia Materials、Phys.org等)。
